DANGER<br />
Grounding the neutral conductor of the generator (N, midpoint<br />
conductor) supersedes the protective measure "protection<br />
separation" <strong>and</strong> should therefore be avoided. If the neutral<br />
conductor N shall be grounded anyway, this may only be<br />
performed by an electrically qualified person. In this case, a<br />
current-operated earth-leakage circuit breaker has to be<br />
connected on the load side of the generator output. The<br />
efficiency of the electrical protective measure has to be<br />
confirmed by an appropriate measurement.<br />
5.3.2 Protection against overcurrent<br />
If the generator is equipped with a control box ex works, the sockets of the<br />
control box mounted on the generator are protected against overcurrent <strong>and</strong><br />
short-circuit conditions using automatic circuit breakers. See Figure 26.<br />
Circuit breaker block<br />
(protection: 3P + N)<br />
